1. Soil Phosphorus Forms and Cycling Are Altered by Acidification from Nitrogen Fertilization in Long-term Wheat Plots in Swift Current, SaskatchewanSoil acidification from high rates of nitrogen (N) fertilization is recognized as a significant problem in many countries, altering many aspects of soil health. However, new research suggests that this is also a problem for soils receiving lower rates of ammonium-N (NH4-N) over long time periods, including on the North American Great Plains. Soil phosphorus (P) cycling is particularly vulnerable to acidification, because P is optimally soluble in soils within a limited pH range. This... B. Cade-menun, L. Bainard |
2. Evaluating Side-Dress N Application Method in SorghumGrain sorghum (Sorghum bicolor L.) is a resilient cereal crop widely grown across the Great Plains, where nitrogen (N) management decisions are often constrained by equipment availability and application timing. While in-season N applications may improve flexibility for producers, concerns remain regarding potential leaf injury (“nitrogen burn”) from high-rate applications. This study evaluated the effects of N source and application... B. Arnall, C. Camacho |
